Re: [vtkusers] MangledMesa & VTK<BR></FONT><BR></DIV>
<DIV></DIV>Well.. Correct me if I'm wrong (/crossfingers hoping i'm wrong) but
I'm trying to get VTk running on systems with no video displays, no hardware
acceleration, and no running x-server. From what I've experienced in the
past (albeit all this testing was back in the 4.4 days), the only way to get
that was with Mangled Mesa. Mesa would get visualizations working
without hardware acceleration, but still insisted on popping up windows (if
you had X running) to do so.<BR><BR>If I could get my visualizations working
(which are all single-frame, render to PNG type stuff) without mangled mesa
I'ld be happy. But, in my experience, there's no way to get it working
in all three cases in a completely "invisible" (meaning no visible display)
way. <BR> 1) Workstation with GPU card & X running, and you're on
the display<BR> 2) Remote system with no GPU card and X not
running<BR> 3) Remote system with GPU & X, but you don't own the
display (connecting in remotely via ssh) <BR><BR><BR>

<DIV></DIV>I've been using MangledMesa with VTK (5.0.1) for quite a while
now with pretty good success, but I ran into an issue where I couldn't get
vtkTextActor's to display in the resulting displays at all.<BR><BR>So I
upgraded to a newer VTK hoping this was fixed (Paraview-2-6 branch) and
recompiled everything. Now my resulting renderings are completely
blank. I did have some issues with getting it to compile as it seems
a few of the files in the Rendering directory have desynced between the
vtkMesa* and vtkOpenGL* versions. I manually resynced them (Just had
to copy some function definitions in the .h files over) and it compiled.
<BR><BR>So my question is a 2 parter:<BR>1) Anyone know how to get
TextActors to work with the 5.0.1 VTK? Was there a known bug around
that time that's been fixed, or is there some new option that must be
enabled to get it to work? <BR>2) How to I get MangledMEsa to work in the
newer VTK releases? Right now i'm getting either blank or
random-garbage displays.<BR clear=all><BR>--
